I purchased these phone 6 months before.I don’t notice any problems in this phone.i purchased these stylish phone from flipkart.16 gb internal storage and 2 gb ram makes the phone lag free.Camera quality of the phone is very good.it comes in 4.3 jelly bean.but tge company provides the updates for lollipop.multi tasking on these phone working perfectly.
One of the disadvantage of these phone is less battery backup.battery drains very fastely.The speaker volume is comparatively less from other phones.The company do not provides head phones.These are some drawback of these phone.otherwise Asus Zenfone 5 is a awesome phone in the market at these price range.
